Oil priming problem

My son and I are finishing up a rebuild of a sbc 350. We have been trying to pre oil the engine with a drill motor. The oil pump seems to be working based on the fact the drill motor is really working hard (to the point of getting very hot) but the oil is not getting to the lifter valley or heads. Anybody have a thought on this?

Are you using a proper priming tool that seals off the lifter galleries? If not you won't get oil up to the lifters. Just a thought

You should at least see some oil seeping onto the rocker arm/push rods.

I have never had a problem priming with a drill, yes the drill gets hot because that is a load for the average drill. I usually screw a hose in where the oil pressure sending unit goes and put a mechanical guage on the other end of the hose so I can read the oil pressure. If you did not soak and prime your lifters by hand before you installed them it will take awhile to get them pumped up with the drill. Let the drill cool off and then try it some more.

Thanks for the input. 85406, the priming tool is just shaft which engages the oil pump. there doesn't appear to be anything to block off the lifter gallery. I bought this tool at my local parts house. Is there a part number you can give me to get the right one?

Try spinning the drill in the opposite direction, maybe you are turning it the wrong direction.

Since he said that his drill is working hard it would seem that it's spinning in the right direction. Spinning in the other direction wont put any load on the drill because it'll be trying to pump air backward through the pump and do nothing but aerate the oil.

I've tried both directions (CW and CCW) CW is definitely harder on the drill motor so I assume that is the correct direction. The tool I'm using doesn't have the two discs shown in your picture 85406, its only the shaft. I guess I need to find one.

If you are not able get a proper primer, you can make one from an old chevy distributor if you have one. Just take the cam gear off, rig it up so that a drill will fit to the top and you are good to use. Another thought would be the fact that the drill got hot means it was pumping oil to the bearings, so you could pour a little oil on the rockers, let some dribble down the pushrods and fired it up with the valve covers loose. It probably will be ok. I wouldn't have a problem doing that with any of my mostly stock motors. I wouldn't do it with my race motor. Make sure when you get it running to check oil pressure and to run it for 20 min at 1800-2500 before shut down.
